From Mean and Median Income to the Most Adequate Way of Taking Inequality Into Account
"... Abstract. How can we compare the incomes of two different countries or regions? At first glance, it is sufficient to compare the mean incomes, but this is known to be not a very adequate comparison: according to this criterion, a very poor country with a few super-rich people may appear to be in goo ..."

Learning to detect natural image boundaries using local brightness, color, and texture cues
- PAMI
, 2004
"... The goal of this work is to accurately detect and localize boundaries in natural scenes using local image measurements. We formulate features that respond to characteristic changes in brightness, color, and texture associated with natural boundaries. In order to combine the information from these fe ..."

these features in an optimal way, we train a classifier using human labeled images as ground truth. The output of this classifier provides the posterior probability of a boundary at each image location and orientation. We present precision-recall curves showing that the resulting detector significantly
A new mathematical model for relative quantification in real-time RT-PCR. Nucleic Acids Res
"... Use of the real-time polymerase chain reaction (PCR) to amplify cDNA products reverse transcribed from mRNA is on the way to becoming a routine tool in molecular biology to study low abundance gene expression. Real-time PCR is easy to perform, provides the necessary accuracy and produces reliable as ..."

Virtual time and global states of distributed systems.
- Proc. Workshop on Parallel and Distributed Algorithms,
, 1989
"... Abstract A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized \ r eal world" and helps to solve problems like getting a c ..."

We argue that a linearly ordered structure of time is not (always) adequate for distributed systems and propose a generalized non-standard m o del of time which consists of vectors of clocks. These clock-vectors are p
The particel swarm: Explosion, stability, and convergence in a multi-dimensional complex space
- IEEE TRANSACTIONS ON EVOLUTIONARY COMPUTION
"... The particle swarm is an algorithm for finding optimal regions of complex search spaces through interaction of individuals in a population of particles. Though the algorithm, which is based on a metaphor of social interaction, has been shown to perform well, researchers have not adequately explained ..."

Collaborative plans for complex group action
, 1996
"... The original formulation of SharedPlans by B. Grosz and C. Sidner ( 1990) was developed to provide a model of collaborative planning in which it was not necessary for one agent to have intentions-to toward an act of a different agent. Unlike other contemporaneous approaches (J.R. Searle, 1990), this ..."

This paper provides a revised and expanded version of SharedPlans that addresses these shortcomings. It also reformulates Pollack’s ( 1990) definition of individual plans to handle cases in which a single
Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

Comparing Lexicalized Grammar Formalisms in an Empirically Adequate Way: The Notion of Generative Attachment Capacity
"... The work presented here addresses the question of how to determine whether a gram-mar formalism is powerful enough to describe natural languages. The expressive power of a formalism can be characterized in terms of i) the string languages it gen-erates (weak generative capacity (WGC)) or ii) the tre ..."

We argue that even SGC is problematic since the sets of trees a grammar formalism for natural languages should be able to generate
The TIGER Treebank
, 2002
"... This paper reports on the TIGER Treebank, a corpus of currently 35.000 syntactically annotated German newspaper sentences. We describe what kind of information is encoded in the treebank and introduce the different representation formats that are used for the annotation and exploitation of the tr ..."

We describe the query language which was designed to facilitate a simple formulation of complex queries; furthermore, we shortly introduce TIGERin, a graphical user interface for query input. The paper concludes with a summary and some
